It is time to address the coil issue. At this stage, I figure using factory specs as a benchmark is decent point of comparison. Factory TJs have 4" of suspension uptravel. With my heavy bumpers, winch and larger tires, I don't have that anymore.
Fortunately, thanks to Unlimited04, mrblaine, bifgnar and others discussing coil lengths and spring rates I realized I can predict which coils I should buy to get back to a minimum 4" of uptravel.
I knew the rates and length of the OME coils I had installed, which meant I could calculate the current sprung weight of my Jeep. After doing the math and measuring my existing uptravel and compressed shock lengths, I arrived at OME 933 for the front and OME 949 on the rear.
This resulted in an even 2" of spring lift with the body lift and 4" of uptravel again before the front tires hit the fenders and the rear shocks bottomed out.
During the process, I did another full bump test and extended my fronts to 1.375" and 1" in the rear. The extensions on the front were moved to the lower spring pad.
Now I am back to factory uptravel, which I am now considering the bare minimum to be maintained for an upgrade.
